During hot work operations, what must be documented in addition to permits?

The requirement to document a log book during hot work operations stems from the need to maintain a clear record of activities, conditions, and occurrences related to the work being conducted. This log serves multiple purposes: it helps in tracking the progress of the work, provides a detailed account of safety measures taken, and can be critical for post-incident investigations if necessary.

Maintaining a log book ensures that there is a formal record of who performed the work, when it was done, any issues that arose, and how they were resolved. Additionally, having this documentation can help in compliance with safety regulations and company policies, showing that there was adherence to safety protocols.

While injury reports, daily weather reports, and witness statements are all important documents in their contexts, they do not serve the same comprehensive purpose as a log book in documenting the specific activities and safety measures associated with hot work operations.
